Abstract
The utility model relates to a seedling separating and transplanting mechanism, the transmission part of which is composed of a crank-rocker mechanism and a planetary gearing system, wherein the crank-rocker mechanism in a gear box of the planetary system drives a sun wheel to rock back and forth; a planetary wheel moves circularly following the gear box and swings back and forth corresponding to the gear box together with the sum wheel so that a planting arm and a seedling pawl fixed with a planetary wheel shaft can satisfy all required operation tracks, seedling obtaining angles and seeding transplanting angles during the rotation of the gear box. The mechanism rotates once to carry out seeding transplanting twice and can be used as the separating and transplanting mechanism for the high-speed seeding transplanter. The mechanism has the advantages of a simple fabrication process and structure and reliable operation.
Description
The present utility model relates to a kind of paddy rice facility of planting of (comprising early rice, late rice), the specifically a kind of crank rocker planet transplanting mechanism that can finish seedling taking when rice seedling plugged in by machine, push away seedling, rice transplanting.
At present, the power rice-transplantor of selling on the market at home and abroad, the form of its planting mechanism mainly contains two kinds: a kind of is crank and rocker mechanism, another kind is off-centre or the elliptic gear planetary system mechanism that uses on the Japanese high-speed transplanter.Domestic crank-rocker style transplanting mechanism, operating frequency can be carried out operate as normal in the time of 200～220 times/minute, along with the increase of rice transplanting frequency, make the aggravation of rice transplanter frame vibration, thereby has limited the raising of operating efficiency.Japan has been owing to added counterweight in this mechanism, and adopts high-strength light material and new technology, and parts design is compacter, exquisite, make Japanese rice transplanter reliable working performance, the rice transplanting quality is higher, and the rice transplanting frequency improves constantly, in recent years above 260 times/minute.But frame vibration aggravates when further improving slotting time, thereby has limited the raising of transplanting work efficient.Planting mechanism seedling needlework speed is too high simultaneously, can produce the inequality of separating seedlings or planting, damaged seedling rate and defectives such as increase of leakage seedling rate and transplant arm rapid wear.
From the eighties, Japan begins to be devoted to the research of novel transplanting mechanism, in order to replace the crank-rocker style transplanting mechanism.Eccentric gear that Japan is developed and elliptic gear planetary system transplanting mechanism are exactly representative wherein.These two kinds of mechanisms, because transplant arm is the center with transplanting mechanism gearcase driving shaft, symmetry is installed, mechanism's good dynamic balance, stable working is vibrated little; During work, rice transplanting twice but driving shaft rotates a circle, and makes seedling needlework speed reduce 1/2 under the situation of increasing work efficiency, thereby realize that damaged seedling rate is low, and the precision of separating seedlings or planting improves, and the rice transplanting quality is good, and agrotechnique requires to be guaranteed.These two kinds of planetary gear type transplanting mechanisms, patent has all been declared in China by Japan.Present homemade trans-planter separate is inserted the low and only seedling operation (is the early rice rice transplanting in south) of suitable rice seedling of mechanism efficiency, can only insert a season at China's southern area of the double cropping rice of planting, so its scope of application reduces greatly.
The purpose of the present utility model is to provide the transplanting mechanism of a kind of simple in structure, easy to process, reliable operation, rice transplanting efficient height, low cost of manufacture.
The purpose of this utility model takes following scheme to realize: described transplanting mechanism transmission is made up of two parts, crank and rocker mechanism and epicyclic train mechanism, crank length is exactly the distance of driven gear axle center to the driving gear axle center in this device, and rocking bar length is exactly the distance of sun gear center to the pin center fixed with it.To crank, driving gear, gearcase and central shaft are fixed by a pair of gear drive power for crank and rocker mechanism, rotate with central shaft.Driven gear and crank one, rocking bar is substituted by sun gear, and sun bye is enclosed within on the central shaft, can drive lower swing at connecting rod.Planetary gear and transplant arm are fixed, and be different with traditional epicyclic train, the swing of its sun gear, and by the swing of mid-wheel drive planetary gear, transplant arm rotates and with the circular motion at planetary gear center, has formed the motion of seedling pawl relative to planet wheel spindle.The parameter of optimizing structure can obtain the desired work track of rice transplanting, seedling taking angle and rice transplanting angle.
The utility model is compared with existing crank-rocker style, and its symmetric arrangement has determined that with rotatablely moving its inertia force is less, can reach the requirement of high-speed transplanter transplanting mechanism.Insert twice because it whenever rotates a circle, after slotting inferior the doubling of its unit interval, seedling pawl velocity variations is little.Compare with Japanese high-speed transplanter eccentric gear planetary system transplanting mechanism, no backlash changes the vibration that causes, its spur gear processing is simpler than eccentric gear.Compare with Japanese high-speed transplanter elliptic gear planetary system transplanting mechanism, processing technology is simple, and disposable less input.
Owing to adopt such scheme, can realize the desired seedling pin of rice transplanting track, satisfy southern and northern needs simultaneously, transplanting mechanism is simple in structure, reliable.
Below in conjunction with drawings and Examples the utility model is further specified.
